In keeping with the principles of Newspeak, all of the words listed here serve as both nouns and verbs; thus, crimethink is both the noun meaning "thoughtcrime" and the verb meaning "to commit thoughtcrime". To form an adjective, one adds the suffix "-ful" (e.g., crimethinkful) and to form an adverb, "-wise" (e.g., crimethinkwise). There are some irregular forms, such as the adjectival forms of Minitrue, Minipax, Miniplenty, and Miniluv (Ministry of Truth, Ministry of Peace, Ministry of Plenty, and Ministry of Love, respectively – all ministries of the active government in Nineteen Eighty-Four).

To say that something or somebody is the best, Newspeak uses doubleplusgood, while the worst would be doubleplusungood (e.g., "Big Brother is doubleplusgood, Emmanuel Goldstein is doubleplusungood").

The word bellyfeel means a blind, enthusiastic acceptance of an idea. The word likely comes from the idea that any good Oceanian should be able to internalise Party doctrine to the extent that it becomes a gut instinct – a feeling in the belly.

Consider, for example, such a typical sentence from a Times leading article as "Oldthinkers unbellyfeel Ingsoc." The shortest rendering one could make of this in Oldspeak would be: "Those whose ideas were formed before the Revolution cannot have a full emotional understanding of the principles of English Socialism." But this is not an adequate translation. ... Only a person thoroughly grounded in Ingsoc could appreciate the full force of the word bellyfeel, which implied a blind, enthusiastic, and casual acceptance difficult to imagine today.

this word has two mutually contradictory meanings. Applied to an opponent, it means the habit of impudently claiming that black is white, in contradiction of the plain facts. Applied to a Party member, it means a loyal willingness to say that black is white when Party discipline demands this. But it means also the ability to believe that black is white, and more, to know that black is white, and to forget that one has ever believed the contrary. This demands a continuous alteration of the past, made possible by the system of thought which really embraces all the rest, and which is known in Newspeak as doublethink.

— Orwell, 1984

The word is an example of both Newspeak and doublethink. It represents the active process of rewriting the past, control of the past being a vital aspect of the Party's control over the present.

The ability to blindly believe anything, regardless of its absurdity, can have different causes: respect for authority, fear, indoctrination, even critical laziness or gullibility. Orwell's blackwhite refers only to that caused by fear, indoctrination, or repression of one's individual critical thinking ("to know black is white"), rather than caused by laziness or gullibility. A true Party member could automatically, and without thought, expunge any incorrect information and totally replace it with true information from the Party. If properly done, there is no memory or recovery of the Incorrect information that could cause unhappiness to the Party member by committing thoughtcrime. This ability is likened to the total erasure of information only possible in electronic storage.

Crimethink is the Newspeak word for thoughtcrime (thoughts that are unorthodox, or are outside the official government platform), as well as the verb meaning "to commit thoughtcrime". In the appendix is noted that the entire United States Declaration of Independence would be translated into the word crimethink, as an idiomatic translation would turn the document into an essay on the virtues of totalitarian government.

Duckspeak is a Newspeak term meaning literally to quack like a duck or to speak without thinking. Duckspeak can be either good or "ungood" (bad), depending on who is speaking, and whether what they are saying is in following with the ideals of Big Brother. To speak rubbish and lies may be ungood, but to speak rubbish and lies for the good of "The Party" may be good. In the appendix to 1984, Orwell explains:

Ultimately it was hoped to make articulate speech issue from the larynx without involving the higher brain centres at all. This aim was frankly admitted in the Newspeak word duckspeak […]. Like various words in the B vocabulary, duckspeak was ambivalent in meaning. Provided that the opinions which were quacked out were orthodox ones, it implied nothing but praise, and when the Times referred to one of the orators of the Party as a doubleplusgood duckspeaker it was paying a warm and valued compliment.

— Orwell, Nineteen Eighty-Four

An example of a skillful duckspeaker in action is provided in the beginning of chapter 9, in which an Inner Party speaker is haranguing the crowd about the crimes of Eurasia when a note is passed into his hand; he does not stop speaking for a moment, or change his voice or manner, but (according to the changed party line) he now condemns the crimes of Eastasia, which is Oceania's new enemy.

Ownlife refers to the tendency to enjoy being solitary or individualistic, which is considered subversive. Winston Smith comments that even to go for a walk alone or to sing to oneself can be regarded as suspicious.[2]

"Un-" is a Newspeak prefix used for negation. It is used as a prefix to make the word negative, since there are no antonyms in Newspeak. Therefore, for example, warm becomes uncold. It is often decided to keep the word which has a more unpleasant nuance to it when choosing which one of the antonyms should be kept in the process of diminishing vocabulary. Therefore, cold is preferred to unwarm or unhot, and dark is preferred to unlight,[3] even though cold and darkness are not physical phenomena as opposed to light and heat. The Party's choice for the less pleasant versions of an antonym may be interpreted as another way the Party makes its subjects depressive and pessimistic to suppress unorthodox thought. On the other hand, the Party controls one's ability to think negatively by sometimes allowing only the positive term preceded by "un-". For example, the concept of "bad" can be expressed only with ungood. When placed before a verb, "un-" becomes a negative imperative; for example, unproceed means "do not proceed". This is similar to the adding of "mal" for negation in Esperanto.

"Ante-" is added to a word in place of using the word "before" (and literally means 'before' in Latin). For example, "antefiling" would mean "before filing".

"Plus-" is an intensifier, in place of "more" or the suffix "-er" (in some situations). Thus, great or better becomes plusgood.

"Doubleplus-" further intensifies "plus-", so doubleplusgood is used in place of excellent or best.

"-ful" is a Newspeak suffix used to turn another word into an adjective. For example, rapid would be rendered as speedful.

"-ed" is the only method to make a non-auxiliary verb past tense in the A-vocabulary. This decreases the number of words required to express tenses by removing irregular conjugations. Ran becomes runned, drank becomes drinked, etc.

"-wise" is a Newspeak suffix used to turn another word into an adverb. For example, quickly would be rendered as speedwise. Therefore "He ran very quickly" would become "He runned plus-speedwise".

A thoughtcrime is an occurrence or instance of controversial or socially unacceptable thoughts. The term is also used to describe some theological concepts such as disbelief or idolatry,[4] or a rejection of strong social or philosophical principles.[5]

An unperson is a person who has been "vaporised"; who has not only been killed by the state, but effectively erased from existence. Such a person would be written out of existing books, photographs, and articles and the original copies destroyed, so that no trace of their existence could be found in the historical record. The idea is that such a person would, according to the principles of doublethink, be forgotten completely (for it would be impossible to provide evidence of their existence), even by close friends and family members. Mentioning his or her name, or even speaking of their past existence, is thoughtcrime; the concept that the person may have existed at one time and has disappeared cannot be expressed in Newspeak. Compare to the Stalinist practice of erasing people from photographs after their execution (see photos, right).

(Many of these are in fact merely part of the "abbreviated jargon – not actually Newspeak, but consisting largely of Newspeak words – used in the Ministry for internal purposes", described by Orwell in chapter 4.)

artsem: Artificial insemination.

bb: Big Brother.

crimestop: to rid oneself of unwanted thoughts, i.e., thoughts that interfere with the ideology of the Party. This way, a person avoids committing thoughtcrime.

facecrime: An indication that a person is guilty of thoughtcrime based on their facial expression.
